/**
 * Question:
 * Given a sorted array, remove the duplicates in place such that each element appear only once and return the new length.
 * Do not allocate extra space for another array, you must do this in place with constant memory.

 * For example,
 * Given input array nums = [1,1,2],

 * Your function should return length = 2, with the first two elements of nums being 1 and 2 respectively. 
 * It doesn't matter what you leave beyond the new length.
 *
